The WdfFdoUnlockStaticChildListFromIteration method unlocks the list of child devices for a specified device and processes any changes to the list that the driver made while the list was locked.
Fdo [in]A handle to a framework device object that represents the parent device.
A bug check occurs if the driver supplies an invalid object handle.
Bus drivers that use static bus enumeration can call WdfFdoUnlockStaticChildListFromIteration.
To lock a child list, the driver calls WdfFdoLockStaticChildListForIteration.
Calls to WdfFdoLockStaticChildListForIteration can be nested and must be matched by an equal number of calls to WdfFdoUnlockStaticChildListFromIteration. If a driver adds or removes items from the child list while it is locked, the framework queues these changes and processes them after the last call to WdfFdoUnlockStaticChildListFromIteration.
For more information about static child lists, see Enumerating the Devices on a Bus.
